DOOR CHECK SPECIFICATION forming part of Iietters Patent No. 686,065, dated November 5, 1901.

Application filed June 1, 1901.

To all whom it may concern.-

Be it known that I, WILLIAM K. HENRY, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in a Combined Door Check'and Closer; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in a combined door check and closer, the object being to provide a device adapted for use on either right or left hand doors without any change, adjustment, or alteration of any of the parts of the device, so that the latter as itcomes from the shop can be applied to either a right or left hand door. I

With this end in View my invention consists in the parts and combinations of parts, as will be more fully explained, and pointed out In the accompanying drawings, Figure l is a view in elevation of my improved device. Fig. 2 is a plan view of same. Fig. 3 is a view in vertical section. Fig. 4 is a view in trans verse section, partly in elevation, onthe line ex of Fig. 3; and Fig. 5 is a view in side elevation of the segmental ratchet-disk.

A represents a casing comprising a springchamber A and a liquid-chamber B, the two chambers being integral and preferably 'located at right angles to each other, as shown. The liquid-chamber is preferably provided with an integral head a at one end and a removable head a at the other end, the said chamber being provided at its closed end with the bypass tube 12, carrying the valve b of the usual or any desired form for the escape of the liquid from in front of the piston during the closing movement of the door.

The piston C is located and moves within the liquid-chamber B and is connected by its rod 0 with the crank D on the lower end of the spindle D, the by-pass tube h passing through the piston, so as to discharge the liquid in rear of the piston during the closing operation of the door, the construction and operation of this by-pass pipe being the same as that shown and described in Patent No.

crank D rests normally in line, with the long axis of the center of the liquid-chamber, so that when the spindle is turned in either direction from its position of rest the head of the piston will be drawn toward the spindle, thus permitting the liquid to pass around the by-pass to a position in front of the piston. As the door closes the liquid is forced out through the valved opening' in the by-pass 6o tube, and during the early part of the closing movement a part escapes around the reduced end of the bypass tube; but this passage around the by-pass is gradually lessened as the door closes, so that during the final closthe dividing-wall of the two chambers A and B, through the spring-chamber, and out through the cap E of the latter and carries or is surrounded at itsupper end by the parts which will be hereinafter referred to;

Located within the spring-chamber, at the bottom thereof, is the clutch-ring F. This ring rests on an upwardly-projecting flange F of the casing and is provided at its lower edge with an outwardly-projecting flange F which is provided with a depending lug F 86 adapted to engage the stop F projecting upwardly from the fioor of the spring-chamber. This ring F is also provided with two up- Wardly-projectinglugs fandf, located atunequal distances from the center of the ring and at diametrically opposite points and are adapted to be engaged, respectively, by the dependinglugsf and f on the collar-section H of the clutch, the said collar H being sec-ured on an angular seat on the spindle D, 90 andhence turns with the spindle. viding the clutch-ring F with two upwardlyprojecting lugs located at unequal distances By profrom the longitudinal center of the spindle and providing the collar H with two correspondingly-placed depending lugs it will be seen that each lug on the collar can engage only the correspondingly-placed lug on the ring, thus permitting the collar to make con-.

siderably over a half-revolution without the lugs thereon engaging the lugs on the ring. The same result, however, can be accomplished by one lug on the ring and a corresponding lug on the collar. When two lugs, however, are used on the collar and ring, as before explained, the pressure is applied evenly to opposite sides of the moving parts, thus lessening wear and liability to binding of the parts.

The body of the ring F is provided with a shoulder at and recess 01 for the attachment of the lower bent end of the spiral spring G, while the upper end of the latter is attached to a disk I, loosely mounted on the spindle just below the cap E. \Vith the construction thus far described it is apparent that when the lugs on the collar are moved to engage the corresponding lugs on the ring the depending lug on the latter will be moved away from the stop F on the floor of the spring-chamber, and when the lugs f and f on the collar H move in the direction away from the lugsf f on the ring that the dependent lug F on the ring F remains in contact with the stop F on the floor of'the spring-chamber. Hence when power is applied through the spring in one direction the lug F bearing against the stop F in the floor of the springcasing prevents the ring from turning; but when the spindle D is turned in the opposite direction the .ring also turns therewith through the medium of the collar 11, which, with the ring, forms a clutch and compresses the spring, starting from the lower end of the latter.

Located under the cap E is the disk I. This disk is detachably connected to the upper end of the spring G and is provided centrally with an opening for the passage of the spindle D and in its upper face with an angular socket to receive the depending angular stem J of the ratchet-arm J. l-Ienceby rotating the spindle D in one direction the lower end of the spring will be wound up or compressed, whereas by rotating or turning the ratchet-arm J in the opposite direction the upper end of the spring will be compressed. In order, however, to effect a compression of the spring from either end, it is essential that While one end is being compressed the other end be held against movement. As previously explained, the ring F, to which the lower end of the spring G is secured, is held against movement in one direction by a lug F on the ring engaging a stop F on the floor of the spring-chamber and is moved in the direction in which it is free to turn by depending lugs f f on. the collar H engaging upwardly-projecting lugs f f in the ring. \Vhen, however, the spindle turns inthe opposite direction, the ring is held by the stop F before described. When the spring G is being compressed at its. lower end, its upper end is held against movement by the pin K resting in one of the pin-holes 7c of the ratchet-arm J and engaging the lug M. This arm, as before explained, is seated in an angular socket in the upper face of the disk I, to which the upper end of the spring is flattened and wound or coiled on edge.

secured. Hence it will be seen that by turn= ing the ratchet-arm (which is done by a spanner engaging the teeth of the disk) the spring will be put under tension, and then by inserting the pin K in one of the holes is of the ratchet-arm J the spring G will be held under tension by the engagement of the lower end of the pin K with the lug M, cast integral with the cap E of the spring-chamber. This tension can be increased by simply turning the arm J to the left by the spannerwrench and inserting the pin in one of the holes to the right of the hole it formerly occupied, and the tension can be decreased by first withdrawing the pin K and inserting it in one of the holes to the left of the one it formerly occupied. The pin K is provided with a shoulder which rests on the top of the ratchet-arm J, and the head of the pin projects upwardly, forming an abutment for the lever-arm N.

lVhen the spring is being compressed at its lower end through the lever-arm, spindle, and clutch previously explained, the upper end is held against movement by the pin in the ratchet-arm engaging the lug M on the cap. This lug and pin prevent the rotation of the ratchet-arm in one direction, butleave it free to turn in the opposite direction. Hence when the lever-arm is turned to the left, or toward the pin K, it turns the ratchet-arm and compresses the spring, starting from the upper end. \Vhen the spindle is turned to the left, the collar-section H of the clutch carried by the spindle is disengaged from the ring-section F of the clutch, thus leaving the ringsection held against movement by its engagement with the stop F projecting from the floor of the spring-chamber. When, however, the spindle is turned to the right, or in a direction away from the pin K, the latter, due to its engagement with the lug M on the cap E, holds the ratchet-arm J and the upper end of the spring G, connected thereto, against movement. The movement of the spindle to the right causes the projections on the collarsection of the clutch to engage the projections on the ring-section of the clutch, and thus turn the latter in a direction to coinpress the lower end of the spring. The spring G is preferably of round wire This construction permits of the use of three more coils within the space of the spring-chamber, thus rendering the spring more elastic and easy in its motion without impairing in the slightest its strength. Vith this construction the spring can be put under any desired tension by the ratchet disk and pin, and as this tension or strain is distributed throughout the spring and against both the ratchet wheel and ring no greater power is required to turn the lever-arm in one direction than the other.

It is evident that many slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described; but,
